What source device will it be coming from and what amp, if any, will you be using? Xonar dx > the amp i am recommended > the headphones

Do you know what kind of signature you're trying to find?An Accurate sound stage with a good balance between everything else

I am currently leaning towards picking up the AD900x's since they improve on all of the previous versions faults and seem like a very nice pair of open cans, i have no idea what amp to use though so any input on that would be great, thanks.

Sorry for reviving the thread, I went to a friends and tried out his ma900s and I was impressed with everything especially the comfort but the bass felt a little lacking, out of all the genres I listen to the ones that I listen to the most are probably electronic and hip hop so im wondering if there is anything in this price range that has a better build quality and better depth to the bass that can also add more "life" to the music, probably asking to much here sorry.

Edit: he doesnt own an amp and it was plugged into his x-fi soundblaster soundcard
